Supercontinent

As the ocean was created, and took over more than half the world, that was when life was given. Water is the source of all creation. Without water, life on earth would never exist. The ocean has given a home to so much life on our earth. It houses food for the ecosystem and for us humans. The earth is a water planet, even tho starting of as a molten rock planet the question still needs to be asked, what brought us to life. Evolution is what got us to. And the ocean and water, just happened to…

Introduction I will be discussing the similarities and differences between uniformitarianism and Catastrophism. The debate on these being going on for years. Why these two theories are very different from each other. Catastrophic believe that there was a great worldwide flood. Uniformitarians believe that the world started from the Big Bang Theory. How old is the Earth thousands of years old or billions of years old. Both theories have their own compelling arguments on how…

When all the continents on Earth were one supercontinent called Pangaea, all land species were able to roam freely. As the continents began to drift apart, individuals of the same species were separated and as the climates of the lands changed those species adapted and evolved into new, separate species…

Almost 4.5 billion years ago, the Earth, newly formed, had possibly the hottest climate in the planet’s extensive past. Temperatures were scorching, enough to liquefy rocks. As radioactive elements located in Earth’s core decay, they generate heat and pressure shoving molten rock toward Earth’s surface. Along with bringing molten rock to the surface, volcanoes also released heat and emitted carbon dioxide into the atmosphere, initiating the greenhouse effect which leads on to global warming.…

1. Explain why Earth and other planets were not solid when they formed during the beginning of the Precambrian, approximately 4,600 million years ago (MYA) The Precambrian period was also known as the Hadean and the reason why it was not solid yet was that the planets of the solar system were just starting to form and they were not even solid rocks yet they were just starting to form from dust particles. 2. What was this particular time period called? This particular period was called the…

The Mesozoic Era was a point in time about 252 to about 66 million years ago. During this era, there were three periods. The Triassic period, The Jurassic Period, and The Cretaceous period were all very significant in earth’s evolution. Not just in animals, but in land, plants, climate, and even insects. The Triassic period was the first period of the Mesozoic era and occurred between 251 and 200 million years ago. At this time the earth was very bare. The planet was recovering from an event…

and where plate tectonics makes its biggest changes. The Fordham gneiss was formed a billion years ago (oldest) during the Grenville orogeny (Precambrian) which featured sediment deposits and volcanic activity, which marked the creation of the supercontinent Rodinia (Keary, 2009). Following the Grenville orogeny there was a period of erosion which allowed for a smooth surface for more deposition. When Rodina began to break up by the Iapetus ocean opening through rifting, led to volcanism. As…

time of the dinosaurs. A gas called Atmospheric carbon dioxide was close to the levels we have today. But, during this time the ice caps from the north and south had melted. Which after resulted in raised sea levels. With this time pangea ( A supercontinent to where all the continents were all connected.) was also changing, Australia was breaking away from Antarctica and gradually moving away from the South Pole, closer to the Equator. The major plants that were dominating australia were…

Biogeography It shows how the past and present geographical distribution of organisms played a role in their evolution.Also, how species are distributed in accordance to the genetic relationships they share with other organisms. Marsupials and Placental Mammals Marsupials animals are almost exclusively found in Australia, while Placental mammals are very rare there. There are fossils of marsupials in North America, and South America. 30 million years ago South America and Australia…

computed by Sir Edward Bullard in 1960s later (Figure 2). Later in 1912, Alfred Wegener, a German geophysicist who was the first to propose the continental drift theory with a mechanism, suggested that all the lands were once joined together as a supercontinent – Pangaea, which was surrounded by the ocean – Panthalassa, the ancestor of modern Pacific Ocean. Wegener’s proposed mechanism of continental drift uses the idea of centrifugal force resulted from spinning Earth and inertia of landmass,…
